An access node of the cellular network determines a correlation of an identifier of a user equipment with an entry of a Pending Interest Table maintained by an Information Centric Networking node. The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request at the Information Centric Networking node. Based on the correlation, the access node controls a connection of the user equipment with the cellular network. This may involve deciding whether to release the user equipment to idle mode or paging of the user equipment.

Correlation of user equipment identity to information centric networking request

Method performed by a first network node () for handling content in an Information-Centric Network (ICN). The first network node () operates in a wireless communications network (). The first network node () obtains () an indication about one or more network nodes () where a request for a content by a wireless device () operating in the wireless communications network () is predicted to be received in one or more future time periods. The one or more network nodes () operate in the wireless communications network () supporting ICN. The first network node () then initiates instructing () at least a subset of the one or more network nodes () to obtain the content prior to the one or more future time periods. Also described are a second network node (), a third network node (), and the wireless device (), for facilitating handling the content in the ICN.

Method and device for facilitating handling content in an information centric network (ICN)

An access node () of the cellular network determines a correlation of an identifier of a user equipment () with an entry of a Pending Interest Table maintained by an Information Centric Networking node (). The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request () at the Information Centric Networking node (). Based on the correlation, the access node () controls a connection of the user equipment () with the cellular network. This may involve deciding whether to release the user equipment () to idle mode or paging of the user equipment ().

The invention relates to methods, a wireless communication device and a network node for enabling establishment of at least one Packet Data Network (PDN) connection between a wireless communication device and a communication network. In a first aspect of the invention, a method performed by a wireless communication device of enabling establishment of at least one Packet Data Network (PDN) connection&#x2014;with a communication network is provided. The method comprises submitting, to a node of the communication network, a request to establish the PDN connection, the request being configured to comprise an indication that the request pertains to establishing a PDN connection for transporting Information Centric Networking (ICN) data.

Distinguishing ICN from non-ICN traffic in a mobile network

An access node () of a cellular network receives an information centric networking request of a user equipment () for a data object. The access node forwards the information centric networking request to a local gateway () associated with the access node (). The local gateway () maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (). In response to the user equipment () moving from a coverage area of the access node () to a coverage area of a further access node (), the access node () and the further access node () perform a handover procedure. The further access node () is associated with a further local gateway () maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (). The handover procedure initiates alignment of the pending interest table and the further pending interest table with respect to at least one entry associated with the user equipment ().

Handover initiated alignment of pending interest tables

A method for enabling establishment of at least one Packet Data Network (PDN) connection between a wireless communication device and a communication network, and a wireless communication device performing the method of enabling establishment of at least one PDN connection with a communication network. The method comprises detecting whether connectivity to an Information Centric Networking (ICN) network is available via the at least one PDN connection for transporting ICN data.

ICN connectivity awareness

Systems and methods related to attachment of nomadic network nodes in a cellular communications network are disclosed. In one embodiment, a method of operation of a network control entity comprises receiving an attach request for attachment of a nomadic node to an anchor node, where the attach request comprises information indicative of one or more requirements of the nomadic node related to traffic and/or service demands. The method further comprises determining whether the one or more requirements of the nomadic node can be fulfilled with existing resources of a transport network that are allocated for the anchor node and, if the one or more requirements of the nomadic node can be fulfilled with the existing resources of the transport network that are allocated for the anchor node, sending, to the anchor node, an attach accept message to thereby accept attachment of the nomadic node to the anchor node.

Nomadic node attachment procedure

A Passive Optical Network, PON, comprising an Optical Line Termination, OLT, connected to one or more Optical Network Terminals, ONT, over an Optical Distribution Network, ODN, is monitored by a monitoring device. The monitoring device comprises an Optical Frequency Domain Reflectometer, OFDR, and is arranged to monitor the optical power received by the OLT and the ONTs of the PON, and to perform transceiver analysis of the OLT and the ONTs, combined with an OFDR analysis of the ODN, based on the monitored optical power violating a threshold.
